A woman in India has been diagnosed with a rare condition known as black hairy tongue, which is characterized by a black, fuzzy coating on the tongue. The condition occurs when the small bumps on the tongue, called papillae, grow longer and become stained with bacteria, food, or other substances. While the condition is harmless and typically resolves on its own, it can be uncomfortable and unsightly. It is often caused by poor oral hygiene, certain medications, or tobacco use. Treatment typically involves improving oral hygiene and avoiding the underlying causes.
